I thought folks were being sarcastic about the burn times in a Blaze King.
Nope, it's all true. Here is my current daily operation:
1) Open bypass damper, fill with lots of excellent hardwood (any combination of well seasoned hard maple, beech, oak, ironwood);
2) Close bypass damper after couple of minutes, burn with stat on 3 for about 15-20 minutes;
3) Turn down stat to 2.5 (will have a quite a lot of flame left, some of it being secondary burn at the top of the firebox);
4) Wait another 5 minutes, turn stat down to 2 or just under 2 (a little flame now and then, sometimes rolling secondaries at the top of the firebox near the cat, this will go out fairly quickly);
5) Wait 24 hours;
6) Open bypass, rake coals forward & center, close bypass;
7) Wait 1-2 hours;
8) Repeat.

As it gets colder, I'll run the fans on low most of the time. That takes heat off the stove, prompting the stat to open the air inlet damper sooner/more often, so the burn times will decrease somewhat. Last winter during typical cold days, I would fill at 5 am and again at about 8 pm.
